myFairTunes 6 is the latest iteration of a recent series of cracks for tracks purchased from the iTunes Music Store. It converts your music from the iTunes Music Store proprietary format to MP3s that you can play on any pocket-player, without having to go to the bother of burning your purchased music to a CD and re-ripping them (something that's not practical with expensive audiobooks, anyway). This is presently Windows-only, and only runs in real-time (meaning that it takes 16 hours to rip a 16h audio-book), but they're promising a 6x realtime upgrade with the next version, and a Mac version can't be far behind.
